Our banking & fintech projects

Surf is a company of choice when it comes to mobile banking and trading app development. Check out our recent projects below.

One app for 5 different banks
Bank Zenit is a parent company for five commercial banks. They needed an application that would serve completely different types of customers. To solve this challenge, we built a complex design system taking into account the needs of different audiences.

Real-time cryptocurrency trading platform
Twim is a mobile crypto exchange for both casual and professional cryptocurrency investors. It allows users to monitor price changes, buy, sell, and trade crypto. We made it possible for price quotes to get updated 20 times per second.

Smart banking app on top of legacy backend
We helped Rosbank rebuild its old app using an improved “smart banking” concept. Because some services had to work using the existing backend, we built a middleware server: a layer that connects the new app to both the old and the new backend.

Fintech app design

Finance isn’t as simple as plugging in numbers on a spreadsheet. Financial apps have to be able to display large amounts of data and include complex user flows. Despite the complexity, fintech must make daily financial operations accessible and user-friendly for everyone. And that’s exactly how we design finance apps.


Data integrations

Your app might require integrations with different financial APIs. Some of these APIs are needed to help you verify user identity, some to enable stock trading, and some to move money internationally. With our large expertise in fintech, we don’t only integrate your app with all the needed services. We help you define what services you need to integrate with.


Fintech app development

At Surf, you get a chance to work with some of the best fintech app developers out there. Yes, we know a lot about fintech and mobile app development (both native and cross-platform). But what’s even more important, we know how to build effective work relationships with our clients that last for years.


Quality assurance

When it comes to money and personal data, QA testing isn’t just “nice-to-have” — it’s a must-have. Minor bugs can undermine your app’s credibility. To make sure your banking or finance app is functional, secure, and usable, we cover 80% of your code with auto and unit tests and run up to 50% of test scenarios manually.


Security and compliance

There can be many areas of vulnerability or risk in fintech applications. After all, the financial industry is hackers’ sweet spot. To minimize the probability of hackers attempting to access personal, financial, and banking information in your app, we write secure code and put your application through rigorous assessments.

There was no backend development expertise in our bank, so the work on the server-side fell on different contractors. In the process, we realized that it would be much better to let Surf develop the entire application because they have deep analytics and understanding of our business processes.
